The electrochemical oxidation of atrazine on Ti/SnO2-Sb2O5/PbO2 electrode was studied by cyclic voltammetry in this paper. The electrochemical behaviour of the electrode in sodium sulfate solution and in the mixture solution of sodium sulfate and atrazine has been studied. The experimental results of cyclic voltammetry showed that acidic media was suitable for efficient electrochemical oxidation of...
The electrochemical oxidation decolorization of the azo dye wastewater containing Acid Red G (5-acetylamino-4- hydroxy-3-phenylazo-naphthalene-2,7-disulfonic sodium) was investigated. The effect of the operating parameters, such as applied voltage, dye concentration, electrolyte concentration and temperature, on the dye wastewater decolorization efficiency was analyzed. The reaction dynamics equation...
This paper investigated the effect of ammonia-nitrogen to the removal of phenol by electrochemical oxidation in the Chloride System. The electrode of RuO2-Pt/Ti was used as the anode and a Ti plate as the cathode. The results of cyclic voltammetry experiments showed that the RuO2-Pt/Ti anode had no effect of the direct oxidation for both phenol and ammonia- nitrogen, which suggested that the intermediate...
The electrochemical oxidation of imazethapyr at Ti/SnO2-Sb2O5/PbO2 electrode was investigated by cyclic voltammetry, and the oxidation mechanism of imazethapyr was primarily studied in this paper . Sodium sulfate was used as the electrolyte of the substrate solutions. The experimental results of cyclic voltammetry show that acidic media is suitable for efficient electrochemical oxidation of imazethapyr...
Electrochemical oxidation integrated with dioxygen activation for high-concentrated chlorophenol degradation was studied in an undivided electrochemical reactor. Dioxygen could be activated under the electrocatalysis to generate the stronger oxidants which promoted the contaminants degradation. The stronger oxidants produced were mainly hydrogen peroxide and the concentration was about 0.6 mmol L-1...
